About

XNRG's mission is to help people challenge themselves and break through their mental and physical barriers, whilst providing peace of mind with expertly run events, going the extra mile for every competitor.

Our heartland is multi-day endurance events; we originally started to help people traing for the world's toughest desert footrace, the Marathon Des Sables. Today, we welcome hundreds of competitors across our events, from single day ultra marathons to multi-day events. We can't wait to welcome you!

Brian looks after most of XNRG's event admin and logistics including looking after event bookings and creating routes, route cards and GPS data. He is also always at every event doing so much more than one person should be able to do in one day!

Rich

Richard, XNRG's Course Manager has been a key pillar of the Extreme Energy team since we started in 2009.

Anna and Richard have been friends since their youth and Neil and Richard have been good mates for 15 years. Whilst not an endurance runner Richard does run to keep fit, and enjoys endurance events, but more the sailing type. In 2003 Richard and Neil were part of a 6 man crew that completed the notorious Fastnet Race.
Rich recently accompanied Neil on the Yukon Arctic Ultra where he was part of the support team. A "Pilgrim Challenge" checkpoint it was not!

You will always see Richard with a smile and an encouraging word to all competitors as they make their way around the course whilst running around covering all of our event photography.
